SPACER FOR LINER-PLATES 0F CENTR-IFUGAL CREAM-SEPARATORS.

Specification of Letters Patent.

Patented Jan. 2,1912.

Original application filed June 16, 1909, Serial No. 502,505. Dividedand this application filed April 17,

To all whom it may concern:

Be it known that I, GUSTAF M. ANDERSON, a citizen of the United Statesof America, and a resident of Waterloo, Blackhawk county, Iowa, haveinvented certain new and useful Improvements in Spacers for Liner-Plates of Centrifugal Cream-Separators, of which the following is aspecification.

My invention relates to improvements in centrifugal cream separators,and the object of my improvement is to provide improved spacing meansfor the liner separating plates so designed and formed as to leastinterfere with the inwardly-moving cream particles when separating fromthe full milk under the influence of centrifugal force. This object Ihave accomplished by means which are hereinafter described and claimed,and which are illustrated in the accompanying drawings.

This application is a division of my application Serial Number 502,505,filed June 16th, 1909.

In the drawings: Figure 1 is an enlarged perspective view of one of myimproved spacing-clips for spacing apart the superposed hollow frusta ofthe liner of a centrifugal cream separator bowl. Fig. 2 is an upper planview of one of the frusta forming part of such a liner, showing themethod of arrangement of the spacing-clips thereon to least interferewith the inward movement of cream particles over the surface of thefrustum. Fig. 3 is a central vertical axial section of two of suchfrusta in superposed relation, and spaced apart by means of my saidimproved spacing-clips.

Similar numerals designate corresponding parts throughout the severalviews.

The frusta 9 are of the conical type, and provided on their inner edgeswith projection adapted to grasp removably an axially located inlet-tubeof the liner (not shown). Between such projections are depressions 12suitable to permit a current of collected separated cream to flowtherethrough on its way to the cream-exit of the bowl.

Each frustum 9 is provided with a plurality of slots adapted to receivethe spacing devices 10. The spacing device 10 is formed of a smalldiamond-shaped piece of metal transversely doubled upon itself to formtwo parallel spaced apart angular members or limbs, and so inserted in aslot of the frustum 9 as to direct the apices of the limbs toward theouter edge of the frustum. The limbs of the device when inserted, arepressed down and clenched tightly upon the opposite surfaces of thefrustum, where they may be soldered or tinned over if desired to securethem in place. This arrangement of the spacing devices orclips 10 withtheir apices directed radially away from the axis of the frustum affordsthe least resistance to the inward movement of the separating cream, andthus aids in preventing the clogging of the liner inter-spaces withclotted cream when the cream is either naturally thick and rich or whenit is by reason of a comparatively low temperature stiffened in itsconsistency.

The spacing clips are easily made and applied to the frusta, and may bearranged thereupon in any desired way, and may be of varied forms otherthan that shown, without departing from the principle of my invention,provided that such clips are so formed as to gradually diminish indimensions away from the axis of the bowl.

Having described my invention, What I claim as new, and desire to secureby Letters Patent, is:

1. In a centrifugal cream separator bowl, liner separating plates, andspacing means located between said plates formed angularly with theapices of their angles directed toward the outer edges of the plates.

2. In a centrifugal cream separator bowl, liner separating plates, andspacers between said plates formed with narrowed outwardly directedparts adapted to stem the inwardly moving cream, as the latter passes tothe cream zone of the bowl over said plates.

3. In a centrifugal cream separator bowl, liner separating plates havinga plurality of slots, and spacing-clips inserted in said slots, theclips being formed to have their projecting portions narrow in width ina direction radially outward from the axis of the bowl.

4. In a centrifugal cream separator bowl,

liner separating plates having each a plu- Signed at Waterloo, Iowa,this 30th day rality of slots, and U-shaped spacers inserted of March,1911.

in said slots each spacer havin its members i gradually narrowed to points with the GUSTAF ANDERSON pointed ends directed outwardly along theWitnesses: surfaces of the plate to stem the inwardly O. D. YOUNG,moving current of cream. G. G. KENNEDY.
